"Fig. 5: Particle level CHI distribution (5.4 < M(JJ) < 6.0 TeV)" of "Measurement of dijet angular distributions and search for beyond the standard model physics in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Normalized CHI = exp(|Y1-Y2|) distributions (1/SIG)*D(SIG)/DCHI in 5.4 < M(JJ) < 6.0 TeV with |Y1+Y2|/2< 1.1 for 138 fb$^{-1}$ of integrated luminosity at $\sqrt{s} = 13$ TeV. The data distributions corrected for detector effects are compared to NNLO predictions with central scale choices $\mu_{F}$ = $\mu_{R}$ = $m_{jj}$ and $\mu_{F}$ = $\mu_{R}$ = $$. Prediction with the alternative CT14 PDF set, and a comparison with the NLO prediction used in the previous publication are also given. Theoretical uncertainties with the central scale $\mu_{F}$ = $\mu_{R}$ = $m_{jj}$ and using NNPDF3.1 are provided. We also provide prediction without EW corrections applied.

针对质心系能量√s=13 TeV、积分亮度为138 fb⁻¹的实验数据，我们构建了满足以下条件的数据集分布：双喷注质量（M(JJ)）处于5.4 TeV至6.0 TeV区间，(|Y1+Y2|)/2 < 1.1，且归一化χ（Chi）分布形式为exp(|Y1-Y2|)，对应微分分布形式为(1/σ) dσ/dχ（其中σ为截面（cross section, SIG））。经探测器效应（detector effects）校正后的数据分布，将与两种中心标度选择下的次次领头阶（Next-to-Next-to-Leading Order, NNLO）预言进行比对：其一为因子化标度μ_F与重整化标度μ_R均取为双喷注质量m_jj，其二为μ_F=μ_R=$$。本数据集还提供了采用CT14部分子分布函数（Parton Distribution Function, PDF）集的预言结果，以及与此前出版物中所使用的次领头阶（Next-to-Leading Order, NLO）预言的比对结果。同时，我们还给出了以μ_F=μ_R=m_jj为中心标度并采用NNPDF3.1部分子分布函数集时的理论不确定性。此外，我们还提供了未施加电弱（Electroweak, EW）修正的预言结果。
